Who did we design them for?

For trail runners seeking ultimate freshness during intense warm-weather runs.

Sustained efforts on technical trails, where foot temperature management drives overall performance.

For those who want zero excessive compression and no trapped moisture in their shoes.

How to wear them?

If you are between two sizes, choose the smaller size to avoid folds that cause blisters.

What sets them apart?

Its strategically placed Coolmax® fibres continuously wick away sweat to keep you feeling fresh from start to finish. Lightweight at 40g, it disappears inside your trail shoe.

Technical freshness, step by step

On trail runs, feet heat up fast. Trapped moisture, hot spots inside your shoes, friction on long outings: the wrong socks cost you valuable energy.

These socks are engineered for continuous wicking. Technical fibres mapped to key zones actively manage heat and sweat. Their anatomical left/right fit prevents bunching right from the first step. Featherlight at 40g, they go completely unnoticed so you can focus all your energy on moving forward.

Because trail performance starts from the ground up. And a dry foot is a foot that keeps the pace.

- Targeted moisture-wicking: heel, toe and arch, keeping you dry from start to finish.

In summary This content is written by AI

Customers first appreciate the comfort: many find them very pleasant to wear, including during a 10 km race, an ultra or after 12 hours in the mountains with boots. Several also praise their good support and well-adjusted fit, including for sizes 40.5 and 43. Lightweight, they wick moisture well and provide a fresh feeling; even when wet in the snow, they go unnoticed. They are well suited to trail running, hiking and summer activities in the mountains.

Première utilisation en terrain sec avec une grosse partie dans la neige. Même mouillée, je ne m'en suis pas aperçu. Très agréable.
